Pressure Relief Valve DBW30B2N5X/100Y6EG24N9K4E - Bosch Rexroth R901143929

A low-pressure circuit fed by a large pump raises a quiet but hard demand: the relief stage must swallow the full flow without letting pressure rise. This pilot-operated pressure relief valve discharges up to 700 l/min and limits pressure across a range of 4 to 100 bar.

Benefits

• 700 l/min permitted flow with a setting range that ends at 100 bar.
• Internal hexagon under a protective cap, so the low protection limit is not raised by accident.
• Pilot-operated seat valve holds pressure across the entire flow range.
• Maximum operating pressure of 350 bar as the body limit.
• Electrical unloading at 24 VDC across two switching positions.
• 6.54 kg weight, connection diagram ISO 6264-10-17.

Application

Intended for prefill circuits of large cylinders, flushing loops and low-pressure supplies with high delivery. The concealed adjustment secures the protection limit of the connected components. The solenoid lets the circuit idle pressureless during pauses.
